UAE E-Invoicing for Zoho Books — No Migration Required

TrustBill connects to Zoho Books via OAuth API, pulling invoice data automatically without manual export. The integration supports all Zoho Books invoice types: sales invoices, credit notes, and debit notes. Once connected, every invoice you create in Zoho Books is synced to TrustBill in real-time, converted to PINT-AE XML format, validated against FTA requirements, and submitted to the accredited ASP network. The entire process is automated — no manual intervention required. You can continue using Zoho Books for all your accounting workflows: invoicing, payment tracking, reconciliation, and reporting. TrustBill operates as a compliance layer on top, ensuring every outbound invoice meets the 2026-2027 mandate requirements.

Setting up the Zoho Books integration takes less than 5 minutes:

1. **Create your TrustBill account** — Sign up for free (no credit card required). 2. **Navigate to Sources** — Go to the Sources page in your TrustBill dashboard. 3. **Select Zoho Books** — Choose Zoho Books from the ERP integration list. 4. **Authorize connection** — Click Connect to authorize TrustBill access to your Zoho Books account via OAuth. 5. **Configure sync settings** — Choose which invoice types to sync (sales, credit notes, debit notes) and set sync frequency (real-time or hourly). 6. **Test submission** — Create a test invoice in Zoho Books and verify it appears in TrustBill with PINT-AE validation.

The integration uses OAuth 2.0 for secure authentication — TrustBill never stores your Zoho credentials. You can revoke access at any time from your Zoho Books settings.

TrustBill automatically converts Zoho Books invoices to PINT-AE XML format, the UAE's national e-invoicing standard. The conversion handles all required data elements: invoice UUID, issue date, seller/buyer TRN, line-item details, VAT rates, and UAE-specific fields like free zone flags and margin scheme indicators.

Zoho Books stores invoice data in its native format, which differs from PINT-AE requirements. TrustBill's mapping engine transforms Zoho data structures to PINT-AE specifications, ensuring every field is correctly populated. The system validates each converted invoice against the FTA's 51 mandatory data elements before submission, catching errors like missing TRNs, invalid VAT rates, or incomplete line-item details. Validation errors are reported in the TrustBill dashboard with clear explanations, allowing you to fix issues in Zoho Books and re-submit.

TrustBill's Zoho Books integration includes:

- **Real-time sync** — Invoices appear in TrustBill seconds after creation in Zoho Books. - **Bulk processing** — Handle high-volume invoicing without manual intervention. - **Error handling** — Validation errors are flagged with clear explanations and suggested fixes. - **Status tracking** — Monitor submission status (pending, submitted, accepted, rejected) per invoice. - **Rejection management** — Rejected invoices can be corrected in Zoho Books and re-submitted automatically. - **VAT 201 integration** — Submitted invoices auto-populate your VAT 201 return draft. - **Multi-entity support** — Connect multiple Zoho Books organizations to a single TrustBill account. - **Data residency** — All invoice data stays in UAE (AWS me-central-1).

The integration works with all Zoho Books editions: Standard, Professional, Premium, and Enterprise.
